SAW-CLEANER FOR COTTON-GINS.

QEECIFICATION forming part of Letters Patent No. 304,304, dated September 2, 188%.

Application filed December 31, 1883. (No modcLl T0 at whom it may concern Be it known that I, RUSSEL M. DORSEY, a citizen of the United States, and a resident of Alpine, in the county of Chattooga and State of Georgia, have invented certain new and useful Improvements in Saw-Cleaners for Cotton-Grins; and I do hereby declare that the following is a full, clear, and exact descrip-, tion of the invention, which will enable others skilledin the art to which it appertains to make and use the same, reference being bad 'to the accompanying drawings, which form a longitudinal sectional View of a modification of my invention.

Similar letters of reference indicate corresponding parts in all the figures.

My vinvention relates to devices for clearing or cleaning the teeth of cotton-gin saws from the gum or deposit which collects upon the said teeth when in operation; and it consists in the improved construction of a device of the above-mentioned class, as will be hereinafter more fully described and claimed.

In the accompanying drawings, A represents the frame or outer casing of the cottongin, B the saws, and O the rotating brushcylinder, the saws B being secured upon their drive-shaft B in the usual manner. The cotton-gin illustrated in the accompanying drawings, and of which the above-mentioned devices form a part, is old and forms no part of my invention, being merely introduced for the purpose of illustrating the operative po-' sition of my improved saw-cleaner. D indicates the saw-cleaner, which consists of the central shaft, E, the extremities of which work in suitable journalboxes in the sides of the outer frame or casing, A, one of the said ends being provided wit-h a pulleywheel, E, through which a rotary motion is communicated to the sawcleaner from an endless belt, F, passing around aband'wheel, G, on the end of the saw-shaft, the pulleywheel or band-whee1 E being preferably only about one-fourth of the diameter of the band- Wheel G, by which arrangement the sawcleaner is caused to revolve four times as rapidly as the saws, as will be readily understood.

' H indicates the end pieces or disks, and H the central disk, which support the longitudinal slats I of the saw-cleaner. Upon the outer surface of these slats are rigidly secured the transverse blocks J, wedge-shaped in section, the slats being further provided with apertures K upon either side of the blocks J.-

L represents the clearing or cleaning pads, which may consist either of a series of strips of leather or other suitable material, curved around the blocks J, and having their ends firm.- ly secured in the holes K by means of small wedges L, as clearly shown in Fig. act the drawings, or of a single strip, M, of leather or other suitable material curved over the tops of the blocks J, in the manner shown, and having their doubled or loop portions, which extend down through the apertures, secured by means of pins M, as shownin the modification Fig. 5. A

From the foregoing description, taken in connection with the accompanying drawings, the construction of my improved saw-cleaner for cotton-gins will readily be understood without requiring further explanation. The saw-cleaner is revolved by the endless belt F in the same direction as the saws of the gin, and, as previously stated, about four times as fast.

By the use of my improvedsaw-cleaner the saws are always kept perfectly free from gum, and any quantity of wet cotton may be ginned without having to stop to clean the saws, as would otherwise be the case, thereby effecting a great saving in time.

It will also be seen that my improvement is simple in construction, and is therefore not liable to break or get out of order.

It is obvious that I do not confine myself to the exact position or location'in which the sawcleaner is to be secured in the cotton-gin, as that would necessarily vary with the form of gin used.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States A saw-cleaner for cotton-gins, comprising a central shaft, two or more disks secured upon the said shaft, a series of slats supported and secured upon the peripheries of the said disks, having a series of blocks secured upon their outer faces, and provided with a series of apertures arranged upon either side of the said blocks, and a series of pads consisting of strips RUSSEL M.
